24 mg mainly, I have a bottle of 18 mg as well, and I think I can tell the difference.
My wife says I look like a druggie with my little bottles and razor blades, etc.!
That's hilarious, but I get it. My wife called it my "paraphernalia". I have a pill-sorter style box, with carts, atomizers and eye-droppers all tucked away. I've seen some folks suggest an actual pill-sorter - seems like a good idea.
Congrats and good luck!
